  • Lecture 1.2: Introduction to Relational Data Model

Week 2 - Thursday (9/4)

• Introduction to Relational Algebra (Chapter 2)

Week 3 - Monday (9/8)

• Introduction to Relational Algebra and Normalization (Chapter 2 and 3)

• (Optional) Videos)

  • Lecture 3.1: Relational Algebra (Join)

    (Errata: Note a mistake at 10 minute mark: hid=hid1 should be hid<>hid1, like in the first solution to the same query.

    This is why, due to inequality, we cannot use natural join for this query easily.)
